airbag warning light 9445417 ->passenger airbag switch.

[atopman]

HI all, i googled the error code and it apparently indicated passenger front airbag switch. I had also noticed if you tapped the switch, the indicator light in the dash would come on/ off, and if you went over a bump or something it would scome on / off by itself.

I took out the switch, ( i have read you are supposed to disconnect the battery first) you have to use plastic tool and insert left side and right side of switch to release the tabs, then the switch can be eased forward, no need to take out glovebox.

I opened up the switch, 4 tabs, carefully separate to keep the spring in place, and mark the pieces for easy assembly later, and eased out the pcb, two tabs, and saw there was no solder on the pins !!!!! so i soldered the 3 pins in properly, and also metered the two microswitches, which appeared to work okay. whilst at it, i resoldered the board under the swicthes. I put it all back and cleared the codes with my Carista, it looks okay, but time will tell. Now i have the AC to sort out. Hope it helps someone, theres a youtube video by a russian guy similar but he takes out the side, and replaces the switch.

Add solder?

yes
" there was no solder on the pins !!!!! so i soldered the 3 pins in properly,"

i didnt take a pic of that sorry, but its easy enough with a soldering iron/ solder, you have to make an electrical connection
at the base of the pins with the circuit pad on the pcb junction.

can anyone help with the other codes? how can i get a cheap vag com cable ?

update:
the airbag ight came back on, i think after a while ?
this time i metered the resistors on the pcb, one looked short circuit ?

A friends code reader confirmed 9445417 manufacturer specific, it said switch out of range, or something similar.

This time i replaced it. I didnt disconnect battery. I got one off ebay £10 and replaced it, and cleared the code.
It hasnt come back, been a couple of weeks.

UPDATE: 2023. been a long while, the new replacement switch seems to have worked ! hope it helped someone else
